Not even GNOME itself could ignore the GNOME 3 criticism for much longer. "As part of the planning for the DropOrFixFallbackMode feature, we've decided that we will compile a list of supported gnome-shell extensions. This will be a small list, focused on just bringing back some central 'classic' UX elements: classic alt tab, task bar, min/max buttons, main menu. To ensure that these extensions keep working, we will release them as a tarball, just like any other module."

I used GNOME 3 (on Fedora Linux) for the first time last weekend. I can give you two very specific reasons why I didn't like it:

It took more mouse clicks and more mouse movement to use my computer. It was very tiring, but I suppose I may have been using GNOME 3 "incorrectly".

It came with an "Accessability" icon in the tray area. I have no need for accessability options (I'm not seeing-impared, and so on) so I wanted to remove the icon. To remove it, I had to do an Internet search and then edit an obscure un-documented file.
